[Working off the latest 5.3 version..]

The man page is out of date, and the input part of the code could use
some cleanup to accept the common lat/lon types:

DDDdMM'SSSS"
-ddd mm ssss 
ddd:mm:ssssW

etc. etc. etc..
I guess checking for both the GRASS ":" way and the format cs2cs uses
should be the target.


For now, use decimal input, eastings first, in the infile & see how that 
goes, e.g:

-100.0000 45.0000 any other data is just passed through
-100.5000 45.2120 any other data is just passed through
